El tampón de lisis y extracción RIPA Thermo Scientific es una formulación plenamente revelada, de alta calidad y lista para su uso de un popular reactivo de lisis celular para células de mamíferos sometidas a cultivo.

Características del tampón RIPA:

Práctico: solución lista para su uso sin necesidad de montar y con componentes que puede preparar usted mismo.
Flexible: compatible con muchas aplicaciones, incluidos los ensayos con indicador, los ensayos de proteínas, los inmunoensayos y la purificación de proteínas.
Versátil: permite la extracción de proteínas presentes en el núcleo, la membrana y el citoplasma.
Formulación pública: no contiene componentes exclusivos, por lo que ofrece a los usuarios un completo control y conocimiento de los posibles problemas de compatibilidad.

Este tampón RIPA lisa y extrae proteínas de manera eficaz a partir de células de mamíferos sometidas a cultivo, incluidas células de placas y células en suspensión peletizadas. Este popular reactivo permite la extracción de proteínas presentes en la membrana, el citoplasma y el núcleo y es compatible con muchas aplicaciones, incluidos ensayos de marcación, el ensayo de proteínas BCA Thermo Scientific, inmunoensayos y purificación de proteínas. Algunos inhibidores, como el cóctel inhibidor de proteasas (ref. 78430) y el cóctel inhibidor de fosfatasas (ref. 78420) Thermo Fisher Halt, también son compatibles con esta formulación de tampón RIPA y se pueden agregar antes de su uso para evitar la proteólisis y mantener la fosforilación de las proteínas.

El tampón RIPA debe su nombre a la aplicación original para la que se diseñó: el ensayo de radioinmunoprecipitación. Si bien este método de ensayo isotópico rara vez se lleva a cabo en los laboratorios de hoy en día, la sigla de la formulación de este tampón de lisis ha perdurado en el uso común. El reactivo de lisis celular RIPA resulta muy eficaz para la extracción de proteínas a partir de una variedad de tipos celulares porque contiene tres detergentes iónicos y no iónicos. Una desventaja de la formulación de este detergente es su relativa incompatibilidad con ciertas aplicaciones posteriores en comparación con otros reactivos de lisis.

Preguntas frecuentes

What are the standard lysis buffers used with mammalian cells for detection of protein expression by immunoprecipitation (IP) or Western blot analysis?

The most commonly used buffer is RIPA Buffer with SDS. We offer RIPA Buffer (Cat. Nos. 89900 and 89901). We also offer the Pierce IP Lysis buffer (Cat. Nos. 87787 and 87788) as well as M-PER (Cat. Nos. 78501, 78503, and 78505).

Does RIPA Lysis and Extraction Buffer (Cat. No. 89900, 89901) contain protease or phosphatase inhibitors?

RIPA Lysis and Extraction Buffer (Cat. No. 89900, 89901) does not contain protease or phosphatase inhibitors. If desired, you may add protease and/or phosphatase inhibitors, such as Halt Protease Inhibitor Cocktail (Cat. No. 78410) and Halt Phosphatase Inhibitor Cocktail (Cat. No. 78420) to the RIPA Lysis and Extraction Buffer to prevent proteolysis and maintain phosphorylation status of proteins. We recommend adding protease and phosphatase inhibitors immediately before use.

Why is it not recommended that I use RIPA buffer for protein A280 measurements with my NanoDrop spectrophotometer?

RIPA buffer produces a particularly strong absorbance signal at the 280 nm wavelength. As a result, it will either over estimate or under estimate protein concentrations and interfere with the protein purity ratio.
Protein samples in RIPA buffer should be quantified via the Pierce Protein 660 or BCA colorimetric assays using a full spectrum NanoDrop model.

Why is there low phosphorylation of the proteins when I use the RIPA Lysis and Extraction Buffer?

Low phosphorylation is usually due to phosphatase activity. We recommend adding a Halt Phosphatase Inhibitor Cocktail to the buffer before use.
Alternatively, the protein is not phosphorylated or phosphorylated at a low level.

What if proteolysis occurs when I use RIPA Lysis and Extraction Buffer?

Proteolysis indicates that no protease inhibitors were added. We recommend adding a Halt Protease Inhibitor Cocktail to the RIPA Lysis and Extraction Buffer before use.

Abstract
Shatavari supplementation in postmenopausal women alters the skeletal muscle proteome and pathways involved in training adaptation.
Authors:O'Leary MF,Jackman SR,Bowtell JL
Journal:European journal of nutrition
PubMed ID:38214710
PURPOSE: Shatavari is an understudied, widely available herbal supplement. It contains steroidal saponins and phytoestrogens. We previously showed that six weeks of shatavari supplementation improved handgrip strength and increased markers of myosin contractile function. Mechanistic insights into shatavari's actions are limited. Therefore, we performed proteomics on vastus lateralis (VL) samples ... More
